Title: heated grips
Post by: royboy on 18.07. 2014 19:48
Good evening. Can anyone help with this? I would like to fit heated grips to my A7 Shooting Star so that I can extend my riding season. Has any one done this successfully? or would it be to much for the dynamo? I have tried many types and makes of gloves but hands still freeze. Hope everyone is enjoying this super riding weather.
Regards royboy

At 12V, you could maybe power a pair, at open road speed, with lights off.

I agree with TT. Been running Oxford HotHands for a couple of years or more now to make the winters easier, and at 12v it's do-able. I reduced the headlight to 35/35 halogen. Those particular grips need about 35W, so that's 70W gone. The dynamo is good for about 80W continuous at 12v using a DVR2 in my case, so it's a near thing with tail/speedo as well. Not a lot left for battery charging. The ammeter shows we're breaking even or a bit better on the open road, but in town it's not so good.  However, without all lights blazing, no problem at all - and she runs all day like that when it's cold. My fingers think they're great, I haven't fried the dynamo so far, and the battery I'm on at the moment seems to be holding up OK too.

I stopped whipping myself in the cold years ago. Now it has to be exactly 28 degrees, no wind and sunny!

I run my heated grips off a small gel battery in my knapsack.  It lasts for a 40 mile round trip OK.

I use these on a couple of my 12v (as std) bikes:

I do have some Oxford grips on another bike but don't like them much - the material is too hard. These ones can be fitted more discretely and run with whatever outer grips you want. And they are very good. The packaging states they use 40 watts, less than three amps. If someone wants to do the maths on that.

You may find the hot hand wraps a better bet, they get good reviews and heat up quickly because they are not insulated by the rubber gripa. Easy to fit and remove in the summer.

Using LEDs for pilot sop/tail also reduced the dynamo loading too

Back in the 70s I was using a BSA Lightning as everyday, year-round transport.  A solution to cold hands in winter came in the form of an Avon handlebar fairing, as used on those 50s police BSAs.  The type that pushes the headlamp forward and, to be frank, is not the most attractive 'extra'.  Despite the poor aesthetics the impact on keeping the hands warm was pretty good, simply by keeping them out of the breeze.  Oh, and it didn't load the electrics either, of course!

The point about the fairing is a good one, breaking the breeze around your digits makes a big difference. I modify MX hand guards to fit rather than going the whole fairing route.

I also used to have a fairing which coupled with waterproff Mitts allowed me to ride all year round off course I was also A) younger (read dafter ) and B) certainly more hardy than I am now ,from memory , poss flawed by time never seemed to have an issue with cold hands, BobH,

Funny thing I never had cold hands on a bike but used to get white finger at other times.
I did have an Avon full fairing , I recall being advised to watch my speed into corners when  it was on, found out what they meant on the first corner but got round it in a fashion
